Question

What is the change in the internal energy of a gas, which is compressed isothermally ?​

Answer 1

Answer:

isothermal compression of a gas there is work done on the system to decrease the volume and increase the pressure. Doing work on the gas increases the internal energy and will tend to increase the temperature. To maintain the constant temperature energy must leave the system as heat and enter the environment.

Answer 2

Explanation : Isothermal process : It is a process in which temperature of system remains constant. That means internal energy is temperature dependent quantity. Hence, the change in internal energy of gas is zero
